Aristotle, Nicomachean Ethics
H. Rackham, Ed.

[3] Ordinary people identify it with some obvious and visible good, such as pleasure or wealth or honor—some say one thing and some another, indeed very often the same man says different things at different times: when he falls sick he thinks health is happiness, when he is poor, wealth. At other times, feeling conscious of their own ignorance, men admire those who propound something grand and above their heads; and it has been held by some thinkers¹ that beside the many good things we have mentioned, there exists another Good, that is good in itself, and stands to all those goods as the cause of their being good.
